Overview
Made from borosilicate glass, the GLBOT bottle holds 8 ounces and is rated for use from newborn through about age 4, sold as a single unit. The 3-in-1 naming in the title isn't explained by any attribute data.
Glass bottles like this one are chosen over plastic for durability and for avoiding plastic-contact concerns, and an 8-ounce size covers most feeding stages past the newborn months. Treat the 3-in-1 claim as a naming detail rather than a confirmed feature set, since no attribute or description data spells it out.
- 8 oz capacity
- Borosilicate glass
- Newborn to 4yo age range
- Sold individually
Who it's for
Parents who prefer glass over plastic bottles and want one rated across a wide age span. Less suited to anyone who specifically needs the 3-in-1 conversion features spelled out before buying, since that isn't detailed here.
